Stereo Ground Loop Isolator
Reduces or eliminates noise caused by ground loops that exist between multiple components in a sound system that may be grounded in different locations within the vehicle. Also very effective in home audio systems where ground loops between components cause the presence of 60Hz hum.

Installed at input of amplifiers that had ground loop hum issue which could be heard when you were within a few feet of the speakers. Not only did this item not eliminate the hum, it made it much worse - you could hear the "background hum" from the next room. Although it is considered improper practice, and I wanted to avoid doing so, putting grounding cheaters on the amplifier power cords eliminated the noise.

waste of money, buy a better one

Bought this to eliminate a ground loop hum. That it did,,,however at the expense of a loss of low frequency audio response and a considerable loss of level. If you have a rather entry level system it might work for you. However in a reference or high end system, its drawbacks are just too severe for cinsideration. Quite lo-fi.

We have a HAL2000 Home Automation system with Whole House Audio from 2 computers on different power outlets. One pc had been creating a HUM in our audio devices which feed through a major amp for the house and another system for 5.1 for a rec room. ALL HAD THAT DREADED HUM. Put this devise on the pc audio output connections and NO MORE HUM AT ALL!
Best money ever spent!
